When jungling Amumu you need to take lots of cautions because he is very mana dependant and most enemy teams invade. So you ask your teamates to cover and when its 1:30 start heading to wolves and ask your teamates to dps then. Then have one of your teamates to leash blue buff . After you complete blue buff head over to wraiths camp and use your e and w to quickly clear them . Now head to red buff and spam your e w whenever posible and smite it if your smite is up. Now you are ready to gank! head over to mid, top , bot depending on which one is positioned for your gank . You want to ping or advise your team that you are ganking. Once you are ready simply walk in and land your Q , lead with your e and w , your team should help you secure the kill and you have succesfully completed a gank . Now go jungle some camps and keep ganking . Thank you for reading and please like my guide . Again, thanks !!
